I trust this won't get any points for elegance, but in our case, we find the virtual compass on the driver station (straight out of the box) is updated along with the Vision Data, which at present, we don't have, but this seems to get the compass heading updated by stubbing out the vision stuff:
// this comes from the example:
// dds->sendVisionData(0.0,
// gyro->GetAngle(),
// 0.0,
// targets[0].m_xPos / targets[0].m_xMax,
// targets);

// and we are able to swing the needle thusly:
vector<Target> targets;
dds->sendVisionData(0.0, m_Gyro->GetAngle(), 0.0, 0.0, targets);


This uses DashboardDataSender.cpp from the 2010 Image Demo.

Hope it helps,
